I am facing an issue. I have few assets whose finance source are multiple , public funds and internal funds both. I have proposed sub asset creation of main asset for consuming grant budget but issue is sub asset is taking main asset FM account assignments, i have unchecked copy for time dependent fields in relevant screen layout of asset class but still system does not overwrite FM account assignment when creating sub asset of main asset. I am using FMDT_READ_MD_ASSET to derive FM account assignment based on user temp field as asset class and cost center or IO. What i see in trace , system assigns main asset cost center to sub asset in trace despite of the fact that i have entered a statistical IO and cost center in AS11 whose derivation rules are in place. Once i save asset , i also tried re deriving button in AS02 but system doing nothing. In detailed trace log system stops at cost center based derivation of main asset , if i deactivate it temporarily , system derives nothing.
Please guide me what can be the issue
